Unity Custom Projector

This document provides an overview of the custom projector system in Unity, along with installation and usage instructions.

Overview

This package includes a custom projector component that allows for advanced projection effects in Unity. It is designed to be easily integrated into existing projects and provides configurable parameters for customization.

Installation

1. Import the provided .unitypackage into your Unity project.
2. Attach the ProjectorRay script to a GameObject.

Usage

1. Assign the ProjectorRayVertexComputeShader.compute to the ComputeShader field in the component.
2. Assign a Material to the Rendering Material field in the component.
3. Configure the necessary parameters in the Inspector:
   • Texture Width & Height: Specifies the texture size for the projector camera. Higher values improve quality but increase processing load.
   • Depth Cam Near/Far/FoV: Defines the near and far clipping planes and the field of view of the projector camera.
   • Layer Mask: Specifies which objects are considered by the projector camera.
   • Rendering Material: The material projected by the projector.
   • Depth Continuity Threshold: Sets the maximum depth difference where the mesh will be placed.
4. Run the scene to see the projection effect in action.

Performance Considerations

• Increasing the texture resolution will increase the computational load. Adjust the resolution to balance quality and performance.
• If optimization is needed, consider using Unity's Decals system as an alternative.
